Hey, that's pretty cool - Is it possible to easily update the cartridge contents, for someone who owns an EEPROM programmer?- Would it be possible to update the cartridge contents from Atari software, or definitely impossible?

Thankyou kindly! I'll see if that works any better than the other split image I found which currently isnt running. Might be my dodgy hardware, but its working on a Mega... although just using ROM4 in that case.
